    Thanks.

    The fix was actually to remove a conflict with the other ELF notes we
    are starting to generate (in the Xen context) so we can get our act
    together that way. I had no reason to suspect it would have had any
    connection with your boot failure.

    I examined your bzImage and it does not have a multiboot signature,
    in the first 8k.

    I pointed my grub at your bzImage and it booted as far as searching
    for init. The only differences were I don't have video mode 0x263
    so when prompted for something supported I told it to use video mode
    0 instead. My boot partition is (hd0,0) and is just boot, so
    I changed the grub configuration to:

    title Andrew
    root (hd0,0)
    kernel /bzImage-2.6.19-rc1 ro root=LABEL=/ rhgb vga=0x263
    initrd /initrd-2.6.19-rc1.img

    So it feels like a subtle interaction with your hardware, or firmware.
    Do things work better if you don't specify a vga=xxx mode?

    This is a weird problem.
